In the same way that the lock on your front door is an annoyance, I guess.

If you think SELinux is "duplicating all logic" in application code,
I do not think you quite grasp how SELinux works.

If the solution to every serious bug that slips through the cracks of a release
is to disable the package, over time we may not have much left in Fedora.

I know that pretty much all filesystems would be out by now. ;)
